Featuring two Russian composers, the two halves of the Royal Scottish National Orchestra’s programme could hardly have been more different. In the first, pianist Xiayin Wang (pictured below) joined the RSNO for Scriabin’s florid, rarely-heard Piano Concerto.

The Brahms violin sonatas make a perfect spring evening recital. The Second and Third were inspired by a summer retreat, but all three are light, bright and with direct melodic appeal. Violinist Alina Ibragimova and pianist Cédric Tiberghien conveyed that carefree spirit perfectly, the long melodic lines simply but elegantly shaped and the accompanying textures always carefully calibrated.

Kudos, as ever, to Vladimir Jurowski for making epic connections.

Space is big – that seems to be the message of Unsuk Chin’s new oratorio Le Chant des Enfants des Étoiles. The work sets texts, ranging from the Baroque to the present day, concerned with space and scale. The work’s cosmic aspirations are reflected in its performing forces, a huge orchestra with augmented percussion, chorus, children's choir, and, for good measure, a suitably Gothic organ part.

Frederic Rzewski marked his 80th birthday with a visit to the Wigmore Hall, for the premiere of his aptly titled Ages.

It’s as intricate as it is concise. The depth to the architecture of James MacMillan’s Saxophone Concerto – which was given its world premiere this week by saxophonist Amy Dickson and the Scottish Chamber Orchestra – is quite astounding, and all the more so for being packed into three five-minute movements.

Even after the venue’s 30-month refurbishment, you still would not choose the sprawling foyer of the Queen Elizabeth Hall as the prime site for a pre-concert speech. By the time, last night, that Heritage Lottery Fund chair Sir Peter Luff got to say his piece – after Southbank Centre luminaries Jude Kelly, Elaine Bedell and Gillian Moore – the ambient din from a full house gathered to celebrate the QEH re-opening almost drowned his words.

Bach’s Art of Fugue, or maybe Mahler’s Nin^th? Nah - in my book, Rachmaninov’s Symphonic Dances is the greatest last work ever composed. This extraordinary piece gets everything right: a kaleidoscopic summing up of a long career which never lapses into dewy-eyed nostalgia.

Live exposure to centenary composer Leonard Bernstein's anything-goes monsterpiece of 1971, as with Britten's War Requiem of the previous decade, probably shouldn't happen more than once every ten years, if only because each performance has to be truly special. It's been nearly eight since Marin Alsop last conducted and Jude Kelly directed MASS at the Southbank Centre.

Former Royal Philharmonic Orchestra principal conductor Charles Dutoit has been exposed, to little surprise from musicians, as something of a roué whose apparent refusal to take "no" for an answer has rubbed up against the new #MeToo world. So his place in last night's concert was taken by Venezuelan Rafael Payare, not yet 40.
